SEMI-DIRECT PRODUCTS AND BOL LOOP

Demonstratio Mathematica, 1994
The authors first discuss under what circumstances semi-direct products of loops can be formed and then show exactly when a loop is a semi-direct product of a pair of subloops. It turns out that some ad hoc constructions in the literature are in reality semi-direct products.

Direct sums of semi-projective modules

Colloquium Mathematicum, 2012
We investigate when the direct sum of semi-projective modules is semi-projective. It is proved that if R is a right Ore domain with right quotient division ring Q not equal R and X is a free right R-module then the right R-module Q circle plus X is semi-projective if and only if there does not exist an R-epimorphism from X to ...

Direction-Aware Semi-Dense SLAM

CoRR, 2017
To aide simultaneous localization and mapping (SLAM), future perception systems will incorporate forms of scene understanding. In a step towards fully integrated probabilistic geometric scene understanding, localization and mapping we propose the first direction-aware semi-dense SLAM system.

Direct and semi-direct approaches to lepton mixing with a massless neutrino [PDF]

Journal of High Energy Physics, 2016
We discuss the possibility of enforcing a massless Majorana neutrino in the direct and semi-direct approaches to lepton mixing, in which the PMNS matrix is partly predicted by subgroups of a discrete family symmetry, extending previous group searches up to order 1535.

Evaluation des coûts-bénéfices du semis direct des céréales et modélisation économétrique des déterminants de son adoption dans le Saïs et la Chaouia

Revue Marocaine des Sciences Agronomiques et Vétérinaires
Cette étude, menée en collaboration avec l’initiative UM6P–Al Moutmir (OCP-Group), a évalué les performances économiques et agronomiques du semis direct comparé au semis conventionnel pour les principales cultures céréalières (blé tendre, blé dur, orge)

ASSIST: Refinement of a Benefits Navigator Intervention Among Low‐Income Pediatric Oncology Families

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Children with cancer living in poverty experience worse survival and quality of life. Interventions connecting low‐income families to benefits (e.g., Supplemental Nutrition Assistance Program [SNAP] improve health outcomes; yet nearly 50% of SNAP‐eligible pediatric oncology families are unenrolled.

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

Loosely-Coupled Semi-Direct Monocular SLAM [PDF]

IEEE Robotics and Automation Letters, 2019
We propose a novel semi-direct approach for monocular simultaneous localization and mapping (SLAM) that combines the complementary strengths of direct and feature-based methods. The proposed pipeline loosely couples direct odometry and feature-based SLAM to perform three levels of parallel optimizations: (1) photometric bundle adjustment (BA) that ...

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...
